The extended finite element method (XFEM) originally proposed in 1999 is very powerful for discontinuous problems in mechanics, such as crack growth, complex fluid, interface, and so on.
扩展有限元法(extendedfiniteelementmethod,XFEM)是1999年提出的一种求解不连续力学问题的数值方法,它继承了常规有限元法(CFEM)的所有优点,在模拟界面、裂纹生长、复杂流体等不连续问题时特别有效,短短几年间得到了快速发展与应用。

A numerical method was studied to solve constrained continuous minimax problems with a Lipschitz continuous objective function and constrained functions.
研究了带约束连续型minimax问题的数值方法,其目标函数和约束函数都是Lipschitz连续的;建立了针对带约束连续型minimax问题的罚函数法,从而将其转化为无约束两层规划问题,并证明了算法的收敛性;最后,用无约束两层规划问题的区间算法进行求解,给出了数值算例。
